1990 Dodge Ramcharger

I have a 1990 Dodge Ramcharger that dies running down the road, for no apparent reason. It will not start back up for at least 5 minutes or more. It does it more and worse when it rains. Also, it runs smooth when first started up but after it gets warmed up it starts running rough, shaking and bucking some. AND when first started up the acceleration is ok but after warming up the acceleration becomes sluggish. Thanks.

Check and monitor the fuel pressure to rule out the fuel filter and fuel pump, start here

Or do below when it stalls don't wait, to catch it -if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
